I don't think so, as the licence is changed only from the QT 4.5 version 
AFAIK. 

The QT4 component in the /trunk is experimental and has many problems: color 
management has changed in QT4, so colors are incorrect ; some things do not 
display correctly yet ; and on my NVIDIA, QT4 is far slower than QT3, even if 
double-buffering is disabled. For example, moving the side panels in the IDE 
becomes slow as hell. By disabling double-buffering, I noticed a lot of 
useless drawing made by QT 4.4. Maybe these things will be better with QT 
4.5 ? The latest beta driver of NVIDIA fixes some problems, but introduce new 
bugs according to their forum, and I'm not sure that it's NVIDIA fault there 
as the IDE keeps being slow (more than with GTK+ if you can imagine) even if 
XRENDER is disabled.
